The difference between the two different series you are listing, since they are both advertising the same resolution would be, marketing terms used to describe them. Neither one is actually full HD.
I'm not going to make any claim as to which is more reliable. Everybody has anecdotal evidence for their opinions there, and I've hardly any statistical proof on those particular models so... Even if you are looking at a good brand name, even good brand names sell bottom rung models. Also, many different brands of electronic devices come out of the same factories in China, making supposed quality differences rather non-existent. How one treats their devices has a lot to do with reliability.
